Field of the Invention The present invention relates to a power supply system using weather forecast information, and more particularly, to weather forecast information using weather forecast information and selectively using an optimal natural energy power source.

In particular, wind power, solar power, micro-hydro power, etc. using natural energy have been increasing from the global environment and the green energy system of electric power companies. Will increase further in the future.

れ、不安定である。[0003] In the course of promoting the liberalization of electricity, local governments and independent private small-scale generators will embarked on renewable energy-based power generation businesses in the future and supply power to consumers through these businesses. There is a high possibility that energy marketers (eg, brokers, aggregators, coordinators, etc.) will appear. A power generation system using natural energy has absolute advantages such as clean energy and no need for fuel.However, because it uses natural phenomena, its power generation is greatly affected by weather conditions and is unstable. .

It is necessary to minimize the influence of fluctuation due to this natural phenomenon.

十分に発揮できているとは言い難い。In a power generation system using natural energy, except for a large-scale hydroelectric power generation system,
Since they are distributed as small-scale energy in various places, they are used as independent distributed energy and are often absorbed in a large-scale power supply system. It is hard to say that these functions have been fully demonstrated.

Nowadays, advanced technology for weather observation and forecasting and advances in computers and communication systems have made it possible to make detailed temporal and spatial predictions based on precise numerical forecasts.
